Got a question? Go ahead and ask me. There are some questions I can't answer because they're under NDA or because I don't know, but I'll at least tell you that I can't answer your question. Some questions will be answered in the comments. If I find myself writing a lot in response to your question, I'll write a new post.
If you don't ask your question this week (which is to say, the week of 19 November 2007), I don't promise an answer. Life is going to be busy over the next few months. I do this whenever I've got a quiet week in the office, which tends to mean that it happens around US holidays.
